Chemical Information
FooDB Namepalmitaldehyde
DescriptionPalmitaldehyde, also known as 1-hexadecanal, is a member of the class of compounds known as fatty aldehydes. Fatty aldehydes are long chain aldehydes with a chain of at least 12 carbon atoms. Thus, palmitaldehyde is considered to be a fatty aldehyde lipid molecule. Palmitaldehyde is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Palmitaldehyde can be found in a number of food items such as rose hip, lambsquarters, pak choy, and swede, which makes palmitaldehyde a potential biomarker for the consumption of these food products. Palmitaldehyde exists in all eukaryotes, ranging from yeast to humans. In humans, palmitaldehyde is involved in few metabolic pathways, which include globoid cell leukodystrophy, metachromatic leukodystrophy (MLD), and sphingolipid metabolism. Palmitaldehyde is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease.
